' LAWN-SPRINKLER Specification of Letters Patent.

Application filed August 23. 1907. Serial No. 389.901.

To all whom it may concern:

Be it known that I, HARRY T. PACKARD, a

citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful Lawn-Sprinkler, of which the following is a specification.

This invention relates to lawn sprinklers and has for its object to provide a sprinkler in which the water is discharged from the spraying nozzle in the form of a rectangular spray thereby to permit the entire surface of the lawn or other confined area to be uniformly and thoroughly irrigated.

A further object of the invention is to provide a sprinkler having a spraying stem seated within and disposed concentric with the discharge orifice, said stem being provided with a square head for deflecting the water laterally in the form-of a rectangular spray.

A further object is to form the head of the spraying stem with converging water passages which receive a ortion of the water from the discharge oriice and delivers the same in a finely divided state at the center of the rectangular spray.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency as well as to reduce the cost of manufacture.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the ap ended claims. 7

In tlie accompanying drawings forming a part of this specification: Figure 1 is a perspective view of a lawn sprinkler coni tructe d 1g. 2 1s a similar View showing the s rinkler detached from the water conducting ose. Fig. 3 is a longitudinal sectional view of the same. Fig. 4 is a transverse sectional View. Fig. 5 is a top plan view, the course of the water being indicated by the dotted lines andarrows.

The improved sprinkler forming the subject matter of the present invention includes a casing or housing 5 having one end thereof provided with a cylindrical portion or nipple 6 the interior walls of which are threaded at 7 for detachable connection with a hose or similar water conductor 8. L7 The top of the casing 5 is provided with a centrally dis osed discharge orifice 9 while l the lower wa l of the casing is rovided with an integral vertically disposed oss or projeci tion 10 having a socket formed therein the interior walls of which are threaded for engagcment with the correspondingly threaded walls 11 of a sprayingstem 12.

The stem 12 is disposed concentric with 1 the walls of the discharge orifice 9 and is pro- Vided with a square head 13 for discharging the water from the orifice 9 in the form of a rectangular spray, as best shown in Fig. 1 of the drawing. The side walls of the head 13 at the juncture of the stem 12 are curved inwardly and downwardly, as indicated at 14 so that the water discharged from the orifice 9 will come in contact with the walls 14 and be deflected laterally on all four sides of the head.

The head 13 is provided with a plurality of converging water passages 15 preferably four in number, as shown, which extend from the curved walls 14 of the head and open through the upper flat surface thereof, the walls of the passages 15 at the upper surface of the head being inclined laterally at 15 so that the water will be delivered in a finely divided state at the center of the rectangular spray and thus thoroughly sprinkle or irrigate the lawn or other surface.

The head 13 is provided with a marginal shoulder 16 the lower edge 17 of which by contact with the water serves to im art the rectangular shape to the spray an deflect the same laterally over the surface of the lawn.

Secured to or formed integral with the casing 5 are depending feet 18 the free ends of which are bent laterally and provided with terminal perforations for the reception of screws or similar fastening devices 18 .which secure the sprinkler in position on a block or other suitable support 19'so as to prevent the sprinkler from injuring the grass when the device is in use.

It will thus be seen that when water is admitted to the casing 5 the latter will flow around the circular interior chamber 20 and thence ass upwardly and outwardly through the ori 'ce 9 in contact with the curved walls 14 of the head and thence laterally against the lower edge of the marginal shoulder 16 thus delivering the Water in the form of a rectangular spray on the surface of the lawn. As the water is discharged through the orifice 1 9 a portion of the same will pass upwardly Patented Feb: 25, 1908.

' Jghrough the passages 15 and thus thoroughly rinkle or irrigate the lawn at the center of The. s ri ers may be made in diflerent sizes an shapes and may be plated, j apanned or otherwise coated to prevent the metal from corrodingp From the foregoing descri tion it will be seen that there is provide an extremeliv simple, inexpensive andefficient device a nn'rably adapted forthe attainment of the ends in view.

stem being curved inwardly and downwardly and provlded with converging water passages openin throu h the top of the head.

2. A sprin ler -inc uding a casing having an intake and provided with a chamber having a discharge orifice, a rojection extend-ing vertically from one wa of the casing and having a threaded socket formed therein, a shank having its lower end threaded for engagement wlth the walls-of the socket and its upper end disposed concentric with the walls of theorifice, said shank being provided with a rectangular head having converging water assages formed therein and opening throu ii the to of said head.

3. sprinkler including a casing having an intake and provided with a chamberhaving a discharge orifice communicating therewith, a stem disposed concentric with the orifice and provided with a rectangular head t e rectangular spray, as best shown in Fig. 1 of the drawin s.

having converging water assages formed therein and'o enin "throug the top of the head, the wal s of t e passages at the upper surface of the head bemg inclined latera ly.

4. A sprinkler including a casing having one end thereof provided with an enlar ement, the interior walls of which are threa ed for detachable engagement with a water con- :and provided with a substantially rectangular head, the side walls of the head at its uncture with the stem being curved inwardly and downwardly and provided with converging water passages opening through the top of the head.

5. A sprinkler including a casing having an intake and provided with a chamber having a discharge orifice, a stem disposed concentric with the orifice and provided with a substantially rectangular head, the side walls of which are curved downwardly and inwardly. and provided with converging water passages extendin from the curved walls to the top of the hea said head being provided with a marginal shoulder for deflecting the water laterally in the form of a rectangular spray.

' In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two-witnesses.
